Cats Need Animal-Based Protein
Cats are obligate (strict) carnivores and are very different from dogs in their nutritional needs. What does it mean to be an ‘obligate carnivore’? It means that your cat was built by Mother Nature to get her nutritional needs met by the consumption of a large amount of animal-based proteins (meat/organs) and derives much less nutritional support from plant-based proteins (grains/vegetables). It means that cats lack specific metabolic (enzymatic) pathways and cannot utilize plant proteins as efficiently as animal proteins.
Vegan cat food is animal abuse.
